When Raman was a simpleton she did not like him.
When he became the rich n handsome rkb shags did want admire n want Raman .
Even though she had chosen Ashok over Raman ,ignoring her marriage to Raman .
It's a case of the ugly duckling .
Their rejected person's transformation into someone they had never imagined possible .
This is adi's gene .
Remember shags being proud of his dancing genes which she claimed to be hers .
